First Claim
1. A cartridge adapted to contain a medicament, the cartridge further being adapted to be inserted into an associated medication delivery device, the cartridge having an identification code which is identifiable by the medication delivery device, the identification code comprising:
- a plurality of galvanically separated electrode elements arranged on an exterior surface part of the cartridge, the plurality of electrode elements being distributed equidistantly substantially circumferentially,wherein each of the electrode elements comprises a receiver zone which connects galvanically to a transmitter zone such that the receiver zone is adapted to receive electrical input signals, and the transmitter zone is adapted to transmit associated electrical output signals, and wherein the receiver zone of each electrode element is displaced along a first direction relatively to its respective transmitter zone, a magnitude of displacement between the transmitter zone and the receiver zone being representative of the identification code.

Abstract
The present invention relates to a cartridge adapted to contain a medicament, the cartridge further being adapted to be inserted into an associated medication delivery device. The cartridge according to the present invention comprises a plurality of electrode elements arranged on an exterior surface part of the cartridge, wherein an electrode element of said plurality of electrode elements comprises a receiver zone and a transmitter zone, said receiver and transmitter zones being electrically connected. The receiver and transmitter zones are adapted to electrically couple to one or more transmitters and to one or more receivers, respectively, said one or more transmitters and said one or more receivers being arranged on the associated medication delivery device.
